Elastic APM issue - co elastic.apm agent.impl.error.RedactedException: The stacktrace corresponds to where elastic APM detected the exception

Hello Team,
We have onboarded Java application which is spring boot and on React.

Once application onboarded under APM - Errors - we see exception :
Elastic APM issue - co elastic.apm agent.impl.error.RedactedException: The stacktrace corresponds to where elastic APM detected the exception

And also there are few more messages like:
at.reacter.core.publisher.Operators.onErrorDropped(Operators.java.673)

at.co.elastic.apm.agent.reactoe.TracwsSubscriber.onError(Trace subscriber.java:126)

Here is application details
Java version 17
React version 18.3
Spring boot version 3.3.4

How can we resolve this exception ?

Any idea on above exception
